Super skinny sister sat down on a dick half her height

My sister had been doing her exercises on a yoga ball since the morning, without even noticing her brother appearing in the room. The dude stood as if spellbound, carefully watching and getting really excited. Seeing that she was not alone, the chick at first thought of throwing an iron at the uninvited spectator, but then it dawned on her. Why injure him when you can benefit from the pussy hiding in your pants? As subsequent events showed, he wasn’t really hiding there, but was already quite standing and just waiting for people to pay attention to him.
